W310 OHIP Billing Code: Use and Eligibility

1What Is the W310 OHIP Code?

The W310 billing code is designed for limited consultations provided by specialists in Physical Medicine & Rehabilitation. This service typically involves addressing a single, focused clinical question for residents in chronic care hospitals, nursing homes, or homes for the aged. Examples include consulting on issues like a specific contracture, wheelchair-seating concerns, or determining the continuation of spasticity treatment.

These consultations are less demanding than full consultations, requiring substantially less physician time. Despite this, they must still meet all consultation criteria, including a written referral from an eligible provider.

Physicians might overlook this code if focused solely on more complex consultation scenarios. Ensure clear and specific documentation to justify the use of W310.
